我使用Wordpress插件Donate Plus，它在一段时间内还没有更新，而且对于大多数用户来说它不能正常工作。所以我对代码做了一些修改，试图让它再次运行。除了在我的PayPal账户的IPN历史记录中，所有交易都具有“重试”状态并具有404的HTTP响应代码，我的一切工作都很好。PayPal IPN传送状态设置为“重试”HTTP响应代码404
脚本中有一个IPN调试功能，它返回“已验证IPN交易[已完成]“，表明一切都已经完成。但是，我收到了多条调试消息，发送了多条感谢消息以及多条条目到我的MySQL数据库中，所有这些我都认为与“重试”问题有关。
我已经在PayPal中手动设置了通知URL，因为我听说这可以解决一些问题。不过，我仍然遇到同样的问题。
我了解脚本需要将完整的未更改的IPN消息发送回PayPal;即消息必须以相同的顺序包含相同的字段，并且以与原始消息相同的方式编码。但是我不确定如何检查$ postipn返回的内容，以便检查这是否是问题。
我包括在任何人的情况下充分paypal.php下面的脚本能发现什么问题是：

感谢您的回答。根据你上面提到的代码，我已经评论了这一点，并将两个标题设置为“Status：200 OK”，但仍然出现404错误。此外，脚本不会死亡，并且我正在收到以“已验证”状态发送的IPN调试电子邮件，所以我非常确定这不是问题。就其他可能性而言，我确信IPN URL是正确的（点2）。我将检查另外两个问题并尽快回复您。 – Nick 2012-08-10 12:01:19
就重定向问题而言（第3点），我之前将通知URL设置为'http：// www。[URL ...]'，我仍然收到404错误。这是否意味着问题与重定向无关？ – Nick 2012-08-10 12:58:49
关于第1点，处理提交PayPal付款的脚本仅将IPN URL设置在一个地方，这是正确的URL。 – Nick 2012-08-10 13:02:07
